Standard:F436M
Description:
The F436M washer, also known as a hardened steel washer, is a specific type of washer designed for use with high-strength structural bolts. It is similar to the F436 washer but conforms to the metric standard.
Here are the details regarding the F436M washer with plain or Dacromet finish:
Size range: The F436M washer is available in a metric size range, typically specified in millimeters. The common size range for these washers is M12 to M100 in diameter, accommodating different sizes of metric structural bolts.
Finish options:
1.Plain finish: The plain finish refers to a washer with no additional coating or plating. It has a natural steel appearance and does not provide any particular corrosion resistance. Plain finish F436M washers are commonly used in applications where corrosion is not a major concern.
2.Dacromet: Dacromet is a corrosion-resistant coating that provides excellent protection against various environmental conditions, including moisture, saltwater, and chemicals. It is a metal-polymer composite coating that offers high durability. Dacromet-coated F436M washers are suitable for applications exposed to harsh environments or outdoor conditions.
Material: F436M washers are commonly made of hardened steel, which increases their strength and durability. The specific grade of steel used is typically medium carbon steel.
Function: The primary function of the F436M washer is to provide a large load-bearing surface under the head of a structural bolt. It helps distribute the load and protect the underlying material, reducing the risk of bolt failure and providing a more secure connection.
